What's the difference between a flood and a flash flood? Flash floods are distinguished from a regular flood by the length of time it takes for the flood to occur. Under six hours, the flood is referred to as a flash flood. Some can occur within minutes. Areas will not always be able receive a warning that these floods are coming and people can be caught off-guard.
Flood waters are more dangerous because they can apply much more pressure than an ordinary river or a calm sea. This is due to the massive differences in water volume that exist during many floods. In a flood, a lot of water may collect in an area while there is hardly any water in another area.ince there is a great deal of water collected in one area, flash-flood waters tend to move with a great deal of force, knocking people, cars and even houses out of the way. Flash floods can be particularly devastating when a heavy thunderstorm dumps a high volume of rain on a mountain.
